Q

What are the disadvantages of resistivity?

A
  • Historic and contemporary debris causes problems

Q

What are the pros and cons of magnetometry?

A
  • Useful in less disturbed soil
  • Doesn’t work well in urban areas e.g. due to power lines

Q

Name 2 ways decomposition odours can be detected.

A
  1. Cadaver dogs
  2. Field portable instruments
17
Q

What are primary and secondary depressions in grave detection?

A

Primary: entire grave surface
Secondary: Area above thorax

18
Q

What volatile organic compounds are cadaver dogs especially useful at detecting?

A

Putrescine and cadaverine

19
Q

How is vegetation useful in detection?

A
  • Decomposition can cause bleaching of plant life as well as smothering
  • Pioneer and young plants indicate recent disturbances
  • High nitrogen and ammonia levels can cause plant death
  • Damage from digging
